I have been looking at linking speeds and where there are a large amount
of debugging info present in a many different files, I have noticed that
linking time is slow. I investigated a little further and noticed that
almost all of the time is spent doing IO calls. I have been told by some
of my colleges that they have a non GPL linker (which is compatiable with
elf linking) and does not suffer this slow down. Does anyone know what
could be causing this slow down? Could a non standard linker script
causing this huge slow down or is there something I am just missing?
The difference between linking with debugging and without is 3 minutes vs
30 seconds which seems a bit high.
This is with binutils 2.17 and 2.16.1 for a modified powerpc64-linux
